Which American architect designed Fallingwater?

Frank Lloyd Wright designed Fallingwater. Built partly over a waterfall in Pennsylvania, the house is one of the defining works of 20th-century American architecture.

Wright designed the residence in 1934–1935 for Edgar J. Kaufmann Sr., owner of Pittsburgh’s Kaufmann’s department store, and his family. Rather than placing the house across from the waterfall, Wright positioned it directly above Bear Run, making the rushing water part of the everyday experience of the building. Construction was completed in 1937, with a guest wing finished in 1939.

Fallingwater is famous for its dramatic cantilevered terraces, local stone, reinforced concrete, and extensive use of glass. The design is often associated with Wright’s idea of organic architecture: a building should relate closely to its landscape rather than appear separate from it. A common mix-up is to credit the house to Ludwig Mies van der Rohe or Frank Gehry, both major modern architects, but Fallingwater is unmistakably a Wright work. The Western Pennsylvania Conservancy has operated it as a house museum since 1963.
